| Make alias matching the events parser case-insensitive. This is useful
| with the JSON events. perf uses lower case events, but the CPU manuals
| generally use upper case event names. The JSON files use lower
| case by default too. But if we search case insensitively then
| users can cut-n-paste the upper case event names.
| 
| So the following works:
| 
| % perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true
| 
|  Performance counter stats for 'true':
| 
|                305      BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL
